Answer:

The Wind Missouri-Mississippi, The Snake Columbia, and the Green-Colorado drainage.

Explanation:

The wind river ranges of the Wyoming is a major headwaters system of the united states and the rage is home to about 63 glaciers and ten of the largest glacier of the united states are found in this region. The wind river range is about 77% of the area s located in the drainage.

The green river is located in the western united states and forms a green river basin of about 730 miles long and covers much of the Colorado plateaus and the snake river forms in a major area of the Sierra Nevada and the cascade range.

how long would it take a 3.4 kg bike with 79 kg rider traveling at 18.6 m/s to stop if 867 N of force is applied to the brakes?

nalin [4]

Answer: 1.76 s

Explanation:

We have the following data:

$m=3.4 kg+79 kg=82.4 kg$ is the total mass of the bike and the rider

$V_{o}=18.6 m/s$ is the initial velocity

$F=867 N$ is the force applied to the brakes

Firstly, we will find the acceleration $a$ with the following equation:

$F=m.a$ (1)

Isolating $a$ :

$a=\frac{F}{m}$ (2)

$a=\frac{867 N}{82.4 kg}$ (3)

$a=10.52 m/s^{2}$ (4) This is the magnitude of the acceleration, however, since the final velocity is 0 m/s, this means the direction is negative

Hence:

$a=-10.52 m/s^{2}$ (5)

On the other hand, with the following equation we can find the time $t$ :

$V=V_{o}+at$ (6)

Where:

$V=0 m/s$ is the final velocity (the bike stops)

Isolating $t$ :

$t=-\frac{V_{o}}{a}$ (7)

$t=-\frac{18.6 m/s}{-10.52 m/s^{2}}$ (8)

Finally:

$t=1.76 s$ This iste time it takes to the bike to stop

A 1.5 kg ball has a velocity of 12 m/s just before it strikes the floor. Find the impulse on the ball if the ball bounces up wit

Andru [333]

Hi there!

Recall:

Impulse = Change in momentum

I = Δp = mΔv = m(vf - vi)

Let the direction TOWARDS the floor be POSITIVE, and AWAY be NEGATIVE.

Plug in the givan values:

Δp = 1.5(-10 - 12) = -33 Ns

**OR, the magnitude: |-33| = 33 Ns

Approximating the eye as a single thin lens 2.70 cm from the retina, find the focal length of the eye when it is focused on an o

Daniel [21]

The focal length will be = 2.67 cm

The distance between the convex lens or a concave mirror and the focal point of a lens or mirror is called the focal length. It is the point where parallel rays of light meet or converge.

given

u (object distance) = 260 cm

v (image distance) = 2.70 cm

f (focal length) = ?

using lens formula

1/f = 1/u + 1/v

= 1/260 + 1/2.70

= 2.67 cm

The focal length will be = 2.67 cm
